Probability distributions of bump widths for a Gaussian threshold distribution. Top: log of the probability density of Δ values for a Gaussian threshold distribution. (White is high, black low.) Bottom: fraction of solutions which are stable. ($\mathit{Black}=0$, $\mathit{white}=1$.) Parameter values are $\alpha =5$, $B=0.76$, $\beta =3$, $h_0=0.05$, $\kappa =0.5$ and ${\sigma }^2=4$
